useful Furnace-Burner, of which the fol-T lowing is a specification.

This invention is a burner for use within natural gas .or similar fuel maybe utilize to heat a dwell-' ingeither through hot air, hot-water or steam heating s stems.

One object o the invention is to provide a burner of simple construction by which the heat will be confined along the sidesof the furnace, and loss of the same by the *heating of surfaces which will perform no part in the heating of the dwelling will be.

avoided.

A further object of the invention is to provide a burner in which the entrance of cold air to the combustion chamber will be reduced to a minimum so that the heat genfrated will be fully and efliciently utilize A further object of the invention is to provide av device of simple construction by which the burner jets will be-kept free of accumulatiofi of soot or other deposits at all times.

With these and such other objects as will hereinafter incidentally appear, in view, the

invention consists. in certain novel features,

of the device illustrated in the accompanying drawings, all of which will be hereinafter fully described and "subsequently pointed out inthe claims. i

In the accompanying drawings, Figure 1 is a view showlng m improved burner. in elevation, a portion 0 a furnace being indicated in dotted lines so as to illustrate the use of the burner. Fig. 2 is an enlarged vertical section of a portion of the burner. In carrying out my invention, I employ an annular burner bod 1 which may be of any desired size according to the requirements ofany particular place, and is preferably constructed in sections bolted together through registering lugs 2 as shown m Fig. 1. The gas or. other fuel 1s supplied to the burner from a supply pipe 3, which ody 1, and

pro-

leads into the under sideof the in its upper side the burner body is vided wit fuel passes to be ignited and consumed.

I furnace as jet orifices 4 through which the On the inner circumference of the annular burner body I provide the inwardly proectmg lugs 6 which support a holder 7, and a deflector 8. The holder 7 is in the form of a cylindrical body having a plurality of perforationst) in its upper portion and provided near 1ts lower end with a series of outwardly projecting radial lugs or supports 10 upon w ich a mass of refractory material, such as asbestos, fire clay oi slag, indicated at 11, may be supported so as to retard the flow ofthe flame and diffuse the heat in the usual manner. On its inner side, near its lower end, the holder is provided with an internal annular flange or rim 12 which is adapted to rest upon the lugs 6 and thereby support the holdel in its proper position and a so receive and support t e lower end oat the deflector, as clearly shown in Fig. 2. The said deflector L8 'is a cylindrical formation, and is provided with a closed lower end, as indicated at 13, and at its lower end has an outstand 'ing annular flange or shoulder 14 which is adapted to rest on the internal flange or rim 12 of the holder and thereby support the deflector in its roper position. This deflec or 8 may be of any size according to the s e of the furnace and is constructed in sections, as indicated at 15, whereby it may be extended to any height within the .mnafinbe necessary. The deflector serves to co e the flame along the side walls of the furnace, so that there 1s no waste of fuel due to a concentration of the flame at the center of the combustion chamber which would mean a loss of valuable heat units. The deflector may be constructed of any suitable material such as asbestos, fire clay or sheet metal. I prefer to em loy sheet metal owing to its lightness and t e ease with/which it may be handled and its low cost. d

It is thought the advantages of my 1mroved device will be readi y understood mm the foregoing description, taken in connection with the accompanymg drawings. The fuel is sup lied to the burner body and is ignited at t e jet OIlfiCBS'lIl the usual manner so as to produce a flame which will tend to rise from the space between the holder and the side of the fire box of the furnace. The fire balls or refractory ma- Will efi'ectually support the material 11 and prevent the same from dropping upon theburner jets. Sufficient air to support combustion will find its wa through the openings 9 in the holder an around the burner body but the flow of a eat volume of cold air upward through to furnace will be ositively prevented by the imperforate bottom 13 of thedeflector 8.

The device is of a .very simple and cheap construction and is efiicient in operation.

While I have referred to the device as annular and' cylindrical, it is not to be understood that the invention is confined to use in furnaces of a round form as it may be employed in furnaces which have a square or any other horizontal outline;

. Having'thus described my invention, what I claimis 1. The combination" with an annular burner body, of inwardly rojecting lugs on the said body, and a c'y indrical deflector restin upon the said lugs and having an imper orate bottom.

2. The combination with an annular burner body having inwardly projecting lugs, of a cylindrlcal sectional deflector provided at its lower end with an annular ange resting on the said lugs.

3. The combination with an annular burner body having jet openin s in its upper side, of a holder supported y and upon the burner body concentric with the inner wall thereof and provided with outstandin supports near its lower end on its outer si e projecting over the burner body, and refractory incandcscing material restmg on said supports directly over the burner body in the path of a flame from the jet openings in the upper side of the same.

4. The combination with an annular burner body, of a cylindrical deflector supported by and upon the innerwall thereof, and a holder supported by the burner body concentric with and between the said body and the deflector and provided with outstanding projections adapted to su port a refractory material over the burner ody.

5. The J combination with a burner body havin inwardly projecting lugs, of a holder Erovi ed-at its lower end with an internal ange restin on said lugs and provided with outstan ing supports.

6. The combination with a burner body, of a holder supported by and above the burner body an provided with a series of openings through its upper portion and haziling outstanding supports near its lower en In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
